Worked on the unitycatalog/unitycatalog repository to deliver cross-format Delta table interoperability by implementing UniForm metadata support within the DeltaCommit API. This involved designing and integrating new DeltaUniform and DeltaUniformIceberg models, updating the DeltaCommitRepository to handle UniForm metadata during commit operations, and adding validation logic to enforce correct enablement states. The work, primarily using Java and focusing on backend development and API design, included comprehensive unit testing and documentation updates. These changes allow Delta tables to be accessed by other formats such as Iceberg without requiring data conversion, reducing ETL overhead and broadening compatibility across data processing ecosystems.

Feb 1, 2026February 2026 monthly summary for unitycatalog/unitycatalog. Focused on delivering cross-format Delta table interoperability via UniForm metadata in the DeltaCommit API. Key work: introduced optional UniForm metadata support and the DeltaUniform/DeltaUniformIceberg models, with DeltaCommitRepository updates to carry UniForm metadata during commits. This enables Delta tables to be read by other formats (e.g., Iceberg) without data conversion. Major commits include 1e4f7fdf290b2c3f792035fe7fb1c8e54a9fd952 (Add UniForm support to DeltaCommit API) and 18137bcffc33e8f6ed5dcb50f8c80801de4b276d (Add extra validation on deltaUniformIceberg).
